Beware of misleading product

During May 2015, I negotiated with Mary-Helen. She contacted me to sign a contract with their company on an LTE rooter. My main concerns moving from my existing service provider to them were, data usage, download speed and cost. After a month's negotiation and her giving me her word I will be happier, I signed up. The contract taking affect 1/7/2015. Firstly, on the 30 of June, when I wanted to setup my rooter there were no SIM card. They said I can either purchase a SIM card or wait 7 days for them to courier it! <br> Secondly, I had a problem with the so called LTE speed being very low. After a week's communication, a telkom technician came out and sorted the problem. The only problem he could not resolve was the upload speed and I'm still waiting for someone to contact me back. <br> Thirdly, while Mary-Helen and I were negotiating, I told her I had uncapped adsl. She said she can offer me 10gig p.m which will be sufficient as I NEVER in a year used more than 7gig! The 14th of July, my 10 gig was up. Upon my quiry, mobile talk informed me I have to take this problem up with telkom, as they can not check what's going on with the data usage. Their answer, they can't do anything about it!
